FLAME-EXTINGUISHER FOR OlL-STOVES.

SPECIFICATION forming part of Letters Patent No. 424,948, dated April 8, 1890.

Application filed July 12, 1889. Serial No. 317,361. (No model.) 7

To all whom it may concern:

Be it known that I, HENRY HICKS ASHEN- DEN, a citizen of the United States, residing at Waterbury, in the State of Connecticut, have invented. a new and useful Flame-Extinguisher for the Burners of Oil-Stoves, of which the following is a specification.

My invention relates to a flame-extinguisher for oil-stoves, and has for its object to provide a device which may be attached to the wick of the lamp or burner and adapted to extinguish the flame thereof by being drawn over and closed upon the end of the burner-tube as the wick is turned down or depressed,

The improvement consists in the peculiar construction and adaptation of the device,

whereby the extinguishing action is performed evenly and with the utmost precision and the extinguisher is automatically and with certainty removed from the tube of the burner as the wick is elevated, all as hereinafter more particularly described and claimed.

In the accompanying drawings,'forming a part of this specification, Figure 1 is a front elevation of an ordinary burner-tube for oilstoves, showing the wick and elevating mechanism. provided with my improved flame-extinguisher, the extinguisher being removed and in the position it occupies when the wick is lighted. Fig. 2 is an end viewof Fig. 1. Fig. 3 is an end view showing the extinguisher partly drawn over the tube, and Fig. l is an end view showing the extinguisher in position to completely extinguish the flame of the wick. Fig. 5 is a sectional view of Fig. 4. Fig. 6 shows the mode of attaching the extinguisher to the Wickjand Fig. 7 shows the extinguisher detached.

Referring to the drawings, A denotes the burner-tube5 B, the wick; C, the spur-wheel for elevating and depressing the wick.

D is the arbor on which the spur-wheel is mounted.

E is the thumb-wheel, mounted on the said arbor, and F is a case or chamber formed integral with the burner-tube to receive the said arbor and spur-wheels, all of which parts are ordinary, old, and require no further description.

G designates my improved extinguisher, which is a simple plate of sufficient size to wholly cover the end of the burner-tube A,

and having a panel 1' embossed, struck down, or formed in it to fit or slightly enter the tube and retain the extinguisher in position on the end thereof. The panel is placed on one side of a central linelengthwise of the extinguisher, so that when the plate is in place on the burnertube one side overhangs the tube much more than the other, forming a projecting part m, which thus preponderates in weight, and is adapted to tip the extinguisher off from the tube and draw it down on one side thereof,

as shown in Figs. 2 and 3.

In each end of the extinguisher is a perforation n in alignment with the central line through the said panel 2', and thus central over the tube when the extinguisher is in place thereon. The perforations are so made that they come close to the end walls of the tube A inside thereof, and the ends of a finewire loop u are passed upward through the said perforations and bent down on the upper side of the extinguisher. To these loops chains k are attached, which chains at their opposite ends are connected to the wick B. A preferred mode of attaching the chains to the wick is by thrusting pins 1. through the end links thereof into the edges of the wick, as shown in Fig. 6; but they may be sewed thereto or otherwise attached.

The operation of my improved extinguisher is as follows: As the wick is in its normal lighted position, the extinguisher hangs down by the side of the burner-tube, as shown in Figs. 1 and 2; but as the wick is depressed or turned down the extinguisher is drawn up edgewise and over the edge of the tube, as shown in Fig. 3, and then by the further depression of the wick the extinguisher is drawn down snugly on the end of the tube, turning or tipping on the edge of the tube, the same as if it were hinged thereto, until it is stopped by contact with both sides of the tube, the panel '5 settling nicely into the tube. This action of the extinguisher shuts off the flame of the wick evenly, gradually, and smoothly, precisely as if the said plate were hinged to the side of the burner and turned down upon it in the manner .of a lid or cover, which motion is insured by the preponderance of the part m. The chains are at the edges of the wick and do not obstruct the movement of the wick in the tube. As the wick is elevated the extinguisher is released and the overhanging part in by its weight, descending, tips that portion of the plate which is over the end. of the tube upward, as a lid is raised, until the whole plate can slide ott the end of the tube and drop down out of the way of the wick. The projecting partm always insures the removal of the extinguisher, and always to the same side of the tube, and thus it cannot become caught on the end of the tube or lie across the same, or otherwise fail to act or get out of order, but insures the utmost eertainty of action, and may readily be attached to any burner.

I therefore claim- In oil-stoves, the combination, with the burner-tube, the wick, and the mechanism for elevating and depressing the wick, of a flameextinguishing cover or plate adapted to stop, rest upon, cover, or close the upper end of the burner-tube, and having a projecting part or portion overhang ng the tube on one side thereof to weight the plate down on that side and tip and remove it from the tube, and the holding-chains fol-attaching the plate or cover to the said wick, whereby as the wick is depressed the extinguishing-plate is drawn up over the end of the burner'tube to extinguish the ilaine, or is removed from the tube by the action of gravity as the wick is elevated, substantiall y as described.

HENRY HICKS ASIIENDEN.
